FASTENER FOR TIPS OF BILLIARD-CUES.

Application filed November 3, 1919.

To all whom it may concern:

Be it known that we, lVILLIAM FEHLHABER and CHARLES L. SMITH, citizens of the United States, residing at Highlands, in the county of Monmouth and State of New Jersoy, have invented new and useful Improvements in Fasteners for Tips of Billiard- Cues, of which the following is a specification.

This invention relates to an improvement in fasteners for the tips of billiard cues, of the type wherein the tip and a removable block are inserted as a unitary structure in the ferrule of a cue.

The principal objects inview are to provide a fastener which may be cheaply manufactured, whose parts are not liable to derangement, which permits of ready application or removal and in which the tip is held with the utmost security and is not susceptible of loose play.

With the above objects in view, the invention consists of certain novel features of structure, combination and relation which will be set forth hereinafter.

One embodiment of the invention is illustrated in the accompanying drawings, wherein:

Figurel is an elevation of a one having a tip secured thereto by our improved fastener.

Fig. 2 is a detail perspective view of the tip. y

Fig. 3 is a detail view of the tip retaining block. V

Fig. 4 is a vertical section through a one with the tip attached.

Fig. 5 is a vertical section showing the tip in transverse section.

Fig. 6 is a section taken on line 6-6 of Fig. 5.

Similar characters of reference designate like parts throughout the several views.

Referring to the drawings, the one 1 carries at its outer end a projecting ferrule 2 formed with internal threads 3. Aprojecting tenon 4 of the one is adapted to be screwed into the ferrule, the lower edge of the ferrule abutting against an annular shoulder 5 formed on the cue. The ferrule is preferably internally threaded throughout its length and the tenon projects a certain distance therein, in practice suflicient to insure the rigidity of the ferrule relative to the cue.

material has a ball contact surface 7 of the usual form and is adapted to bear upon the outer edge of the ferrule, the same being provided with notches 8 to prevent accidental turning movement of the tip relative to the ferrule but which do not offer appreciable resistance to intentional turning movement of the tip. The tip is provided with an integral lug 9 which is relatively hard and preferably dove-tail in cross-section and has tapering side faces. This lug is of width coextensive with the internal diameter of the ferrule. In case the tip is made of leather, the material constituting the lug may be treated in any known and suitable manner to secure the desired hardness.

Athreaded block 11 preferably cylindrical in shape and of sufficient diameterso as to fit the 1nterior of the ferrule has a groove 12 preferably dove-tail in cross-section and having tapering side walls. This groove is so formed as to provide overhanging flanges 13 which are adapted to cooperate with shoulders 10 formed on the lug 9 to maintain the tip against movement when it has been inserted in the block. As stated above, the lug is preferably formed with tapering side Walls and the groove in the block is similarly formed, this being preferred for the reason that when the lug is inserted in the groove the tip is held against lateral movement in one direction by the converging walls of the groove, thus rendering displacement of the parts less likely when the tip is being inserted in the ferrule. As indicated at 14, the ends of'the lug project beyond the retaining walls of the groove and preferably, the ends of said lug are left smooth surfaced prior to insertion in the ferrule. As the tip and fastener are being screwed into place in the ferrule, threads will be out upon the ends of the lug, there by insuring a firm seating of the tip.

The tip prior to its attachment to the one is inserted in the block, the shoulders on the lug cooperating with the flanges on the grooved block to prevent vertical displacement and the side walls of the dovetailed groove cooperating with the sides of the lug to prevent lateral displacement of the tip relative to the block. The tip and block as a unit may then be screwed in the ferrule by simply turning the tip in. the desired direction, the threads on the block acting in conjunction with the threads in the ferrule to effect that purpose. After-- the plug has traveled the required distance within the ferrule further turning movement of the tip will bring the lower edge of the tip so tightly against the upper edge of the ferrule that the notches formed therein will prevent accidental turning movement of the tip in the reverse direction. Toremove the tip it is turned in the opposite direction until the block has been threaded out of the ferrule.

We claim V 1. In a billard cue tip fastener, the-combination of a-ferrule projecting from the cue, a tip havinga bearing against said ferrule and provided with a lug,.a block adapted tolenter said ferrule and having formed therein a groove for the reception of said lug, said ferrule surrounding said block and lug whereby lateral movement of-the tip is prevented.-

2. In-a billiard cue ti pfastener, the cornbination of a ferrule projecting from the cue and having internal threads, a tip having a bearing against the ferrule and provided with a. lug, and a threaded block adapted to enter said ferrule and having formed thereina groove for the reception of said lug.

3. In a. billiard cue tip-fastener, the com- I bination of. a, ferrule projecting from the cue: and having internal threads,a tip having; a, lug formedthereon and, having a bearing against the ferrule and a block adapted to enter said ferrule; and having formed through the upper face thereof a f dovetail groove for the reception of said binationof a ferrule projecting fromf thev one and havinginterna'lthreads, a tip'hav- 7 mg: a lug formed thereon and having ab'ears,

lug, said ferrule surrounding said block and lug whereby lateral movement of" the tip is":

prevented."

6. In a billiard cue tipfastener, the combination of a ferrulefhaving notchesin its upper edge, a tip having a lug formed there'- on and having a bearing against said ferrule and adapted to engage saidnotches, and. a block adapted to enter said ferrule and having, formed through the upper face thereof a groove for the reception ofsaid lug; 7. In a billiard cue tip fastener, the combination of aferrule projectin'g from thecue and having internal threads, a tip hav' ing a bearing against the ferrule and provided with a lug so formed as to provide retaining slioulders, and a bloclra'da'pted to enter said ferrule and havingforrned therein a groove for the reception of said' lug,

said groove forming, with theiu-pper face 7 of said b'loclr, tip retaining flanges.

8. In a billiard cue tip f st'ener, the-combination of, av ferrule: projecting-from the one and having internal threads, a tip =having a bearingagainstithe ferrule and'provided with a lug-so formed as-to" provide retaining shoulders; and a bloclii adapted to enter said ferrule and havingformed on its upperface a groove adapted to'receive'said" lug, the. ends of said lugheingiso formedas to project beyond the inclosi'ng wal l's of said block. x f
